Utility to find network device with duplicate IP addresses? [Solved]

[CoolHandJoe]

Hi there.

Just wondering if there's a function or utility with pfSense that would monitor the network for a device with a duplicate IP address that had been added to a network. I've seen something like that if the DHCP server is being used but is there one that can tell you when the DHCP server is elsewhere and the duplicate IP is manually entered in both devices?

If not does anyone know where I might find something like that?

Thanks

Joe

Sorry, just found arpwatch. Please disregard question. I haven't deleted it because when I initially searched the forum nothing came up.

Cheers.
